  • Each electromagnetic valve 10 is provided with terminals 12t, 14t, and provided with a pair of terminals (represented by 21t) of the motor 21 at its central portion.
  • the frame 30 is made of synthetic resin to define four rooms (represented by 31) for receiving therein separately every two electromagnetic valves 10, and define a hole 32 for receiving an installation screw 63 in its central portion, and a pair of holes (represented by 35) for receiving the terminals 21t of the motor 21 at its both sides.
  • the frame 30 has a connector portion 33 integrally formed therewith, which extends in a longitudinal direction of the frame 30 out of the plane connected with the valve body 20, and a plurality of through holes (represented by 34) are defined perpendicularly to the connected plane.
  • the frame 30 is so arranged that the frame 30 is secured to the valve body 20 by screwing the screw 63 into an installation hole (not appeared in FIG. 1) of the valve body 20 through the hole 32. Therefore, the valve body 20 and the frame 30 are connected with each other without any screws exposed on their outer surfaces.

  • the conductive members 42, 44, 46, 48 which are arranged to form three layers (46 and 48 are positioned in the same layer), and the insulating members 41, 43, 45 are alternately stacked one over another, and fixed therebetween through a mechanical engagement. Or, those members may be connected with each other by an easily separable adherent material. Accordingly, a sub-assembly is formed to provide the bus bar assembly 40 as shown in FIG. 2.

  • the contact pin 42t and the like are extended out of the outer surface of the insulating member 41 through the openings 41h as shown in FIG. 2, while the connector terminal 40c extends downward as shown in FIG. 2.
  • the cover 50 is made of synthetic resin to be fitted with the configuration of the frame 30, and provided on its outer side surface with a plurality of engaging portions (represented by 51) which engage with protrusions 36 formed on the outer side surface of the frame 30. Also, the cover 50 has a projection 52 which extends from its inner bottom toward its open end as shown in FIG. 3. When the cover 50 is secured to the frame 30 with the bus bar assembly 40 held therebetween, the connector portion 33 is pressed by the projection 52 toward the frame 30.
  • the configuration of the projection 52 is not limited to the one having the cross section as shown in FIG. 3, but may be the one to provide a biasing force against the bus bar assembly 40 when it is pressed between the cover 50 and the bus bar assembly 40, e.g., the one bent at its intermediate portion.
  • the frame 30 is mounted on the top surface of the valve body 20 with the packing 61 disposed therebetween as shown in FIG. 1, and secured to the valve body 20 by the screw 63. Then, the connector terminal 40c of the bus bar assembly 40, which constitutes a sub-assembly as shown in FIG. 2 to the electromagnetic valve unit, is pressed into the through holes 34 of the connector portion 33 to form a connector as shown in FIG. 3. Consequently, a side surface of the contact pin 44t of the conductive member 44, for example, contacts with a side surface of the terminal 14t of one of the electromagnetic valves 10, and then the contact pin 44t and the terminal 14t are electrically connected with each other by welding, for example.
  • the cover 50 is placed on the bus bar assembly 40 with the packing 62 disposed therebetween, and the engaging portions 51 of the cover 50 are engaged with the protrusions 36 of the frame 30, so that the cover 50 is connected with the frame 30 to form the electromagnetic valve unit.
  • the bus bar assembly 40 can be fixed by simply pressing the terminals constituting the connector terminal 40c into the through holes 34 of the frame 30, and the contact pin 42t and the like can be easily formed. Since the bus bar assembly 40 can be easily separated from the frame 30, it is easily adapted for recycling of waste. Moreover, if the components of the bus bar assembly 40 are formed to be separable, its recycling ability will be improved.
  • the electromagnetic valves 10 are disposed symmetrically with respect to the central axis of the connected plane between the valve body 20 and the frame 30. Therefore, when it becomes necessary to provide the connector portion 33 at the left side in FIG. 1, for example, only such a small modification will be sufficient that the frame 30 is disposed with its left and right sides positioned inversely, and that the bus bar assembly 40 is provided with its wiring pattern slightly modified. That is, only the positions of the contact pin 42t etc. formed on the conductive member 42, 44, 46, 48 of the bus bar assembly 40 may be changed to provide the slightly changed wiring pattern. Consequently, without such a large modification as a design change of a printed circuit board, the connector can be easily provided at either side of the electromagnetic valve unit.
